Abstract

A low consumption and intelligent safe gas-supply system for gas tanks comprises: at least two gas tanks and gas tank valves installed on them, charge valves with check valve, at least two gas-filled parallel unit pipes, high-pressure sensor, at least two gas-supply parallel unit pipes, gas-supply main conduit, reset pressure sensor, at least two solenoid valves with check valve, and electronic control module ECM. The invention has the characteristics such as the gas tanks supply gas in sequence, intelligent control, security and reliability for use, low consumption, high display precision for gas volume, decompression transfinite alarm and convenience for installing, use and maintenance etc., and it can be used in the vehicle hydrogen supply system in the fuel cell vehicles or the vehicle compressed natural gas-supply system in the natural gas vehicles, and also the high-pressure hydrogen or natural gas-supply system for gas tanks on the ground.

Description

TECHNICAL FIELD[0001]The present invention relates to a vehicle hydrogen supply system used in fuel cell vehicles or vehicle hydrogen and compressed natural gas supply system used in the natural gas vehicles, and high-pressure hydrogen or natural gas supply system for gas tanks on the ground.BACKGROUND OF THE INVENTION[0002]It is well-known, the oil resources around the world become increasingly depleted, and the development of human society causes great damage and pollution to the environment, which make countries around the world begin to look for more environmental, replaceable and renewable energy sources. Hydrogen, as one of the most abundant element in the universe, is clean, renewable and has high density of energy, and is considered the most promising replaceable energy source in the future. With the improvement of fuel cell technology, hydrogen energy has been used in the vehicles.[0003]The hydrogen supply system is one of the most unsafe factors for hydrogen fuel cell vehi...
